Which mechanism increases flame propagation speed in premixed methane-air combustion?

💡 Explanation

Increased radical pool concentration accelerates the chain reaction because chain branching generates more radicals, therefore flame propagation increases rather than slower propagation with other options inhibiting the radicals.
